To all whom it may concern.

Be it known thatI, ALBERT KRAUTH, a citizen of the United States, and residing at Hamilton, in the county of Butler and State ofOhio, have invented a new and useful Improvement in Manifolding-Machines, of which the following specification is a full disclosure.

The invention herein is primarily directed to devices for engaging through the perforations in the several superposed strips of paper :upon a writing-table, for exact regis-. .tration and ahnement of the prlnted forms on the several strips, for holding the'strlps at opposite ends of the table and tautly stretching the paper upon the table, and

for regulating the distances of successiveadvancement or withdrawal of the paper.

It is particularly adapted to manifolding machines in which usually several webs of paper in a superposed relation are supported upon and drawn over a writing table for manifolding record entries. The webs each contain preprinted. forms and are withdrawn from the machine as the forms are used and severed from the strip or web.

The webs or strips of paper are provided with perforations, usually punched through the paper at the head of each form printed on the strip, as fileholes for each form length when severed from the strip. The

perforations, for the forms of the strip,are

the several superposed strips upon the writ- 1ng-table in registration and ahnementwith each other.

An object the invention is to provide means located at the forward end of the writing table to engage the paper through apertures in registry'with said means for stopping or limiting the paper withdrawal or regulating the distances of the successive advancements of the strip or superposed strips together with devices for engaging through registering apertures located at the the devices engaging the paper at the forrear end of the table and cooperating with ward end of the writing table for confining 1 the paper and maintaining the several superposed paper portions over the table in registration and alinement with each other.

Various other features and objects of the invention will be more fully disclosed by the accompanying drawings and the descrip tion thereof forming a part of this vspecili cation, andin such drawings like characters of referencedenote corresponding parts throughout the several views, of which Figure 1 is a central vertical section of a manifolding machine of a type known to the trade as a pull-out machine, from which the paper is manually withdrawn for a determined length and severed across a tearing blade at the delivery end of the machine.

Fig. 2 is a top plan view of the machine with the margin frame omitted. Fig. 3-is an inside bottom plan view with the base removed to illustrate the parts mounted upon the underside of the writing table. Fig. 4 is an enlarged section on line 4-4, Fig. 2, of the upper portion of the machine and principally through the writing table. Fig. 5 is an enlarged section on line 55, Fig. 3. Fig. 6 is a top plan view, on a reduced scale, of a portion of theweb of perforated paper used in the machine herein described.

The invention herein is illustrated as primarily combined with a type of machine in which the paper is manually withdrawn, as re n'esenting the most simple type, but it is obvious that the'invention is applicable to various other types of manifolding machines providing paper feeding mechanism for withdrawing the paper and therefore I do not necessarily wish to be confined to the type of machine illustrated.

The invention is also somewhat related to the inventions contained-and made the subect-matter of a prior patent issued to me, reissue Nod-L189, dated August 29, 1916, which discloses a member yieldingly urged toward a face, of the paper adapted to engage through a registering aperture in the paper during its withdrawal from the machine to intercept the paper withdrawal.

Referring to the drawings, 1 indicates the base of the machine, 2, 3, side frames providing a casing for the rolls of paper 4, three rolls of paper being shown, but their number being optional depending upon the size and use for which the machine is intended. The side frames are shown as of sectional form, comprisinga pair of forward sections fixed to the base and a pairof rear sections as a .unit fulcrumed upon the forward sections of the side frames. he

and pivoted to the side frames for swinging the blade above the table and rendering accessible the end of the paper beneath the blade. An arm'8 projects rearwardly from the tearing blade providing hand-hold means for swinging the tearing blade. The strips from each roll are respectively fed over the guiding rollers 9, at the rear upper edge ofthe casing and from the rollers forwardly over the writing table to the tearing blade. These parts are common to all manifolding devices. A margin frame, not shown, is usually provided to 'marginally surpround the writing table and cover the guide rollers at the rear upper portion of the machine. The machine along one side is also provided with acarbon holder or receptacle for holdinga supply roll of carbon paper, which is fed across the writing table between the several strips fed from the rolls 4. The strips of paper are provided with spaced apertures longitudinally dividing the strip into sheet lengths or form sizes.

The apertures or perforations are spaced laterally apart in a definite and invariable relation with the printed matter of each form and are usually located at the head of each form to serve as filing holes when the form is severed from the strip. Each strip is composed of a succession 'of independently related forms, each form consisting of printed matter and two laterally spaced holes. In the machine several of these strips are passed, in a superposed relation, over a writing-table, until they are stopped by depressible pins, at the forward end of the writing-table, engaging upwardly through the perforations of the paper, with the effect that all of the forms of the several strips are stopped in the same relation to the pins. Any form of one strip, in advance of a rela tive form of asecond or third strip, will be assisted first and the others will not be arrested until they have moved up into alinement with it. Depressible pins located at the rear end of the writing-table, having a yielding forward motion, are arranged to of the shaft 15.

engage through the apertures or perfora tions of a successive form of each of the several strips and slightly in advance of the engagementof the pins at the forward end writing-table in registration and lateral alinement with each other. The perforations, therefore, provide means of regulating the distances of the successive advancements of the strips and for limiting the withdrawal to the distances between the perforations. e

The forward end of the writing tableis notched as at 9, Fig. 2, to expose the end of the paper so that it may be grasped for paper withdrawal, and also to enable the tension blade 10 fulcrumed upon the crossbar 11 connected to the side frames to engage against the cross-bar or plate 12, supported over the writing table. The tension blade serves as a brake against any reactionary motion of the paper. The tension blade is operated with. the tearing blade,

so that when the tearing blade is in its nor mal position the tension blade is released and free to permit the pin carried by the are fixed to a rock shaft 15 journaled in the side frames and maintained under tension by a spring 16encircling the rock shaft with its ends respectively engaged with the side frame and shaft. for automatically re turnin the tearing blade to its normal position w ien released. The rock shaft 15 has an arm 17 fixed thereto and is adapted to be connected with means for moving the paper arresting devices to a non-paper-engaging position. The arm 17 engages with a lug 18 projected from the'tension blade. for

controlling its position with the movements Thus it will be seen that when the arm 17 moves rearwardly it will release the tension blade to permit it to engage the cross-bar or plate 12 binding the paper and operating as a wedge-bar or pawl to preventrearward movement of the paper.

. Under such control of the tension blade the paper is relieved during the major portion of a withdrawing operatlon.

The paper arresting mechanism is arranged to operate upon the paper at the forward and rearward ends of the writing table, embodylng devices adapted to engage through registering apertures 1n the paper.

The forward devices primarily the withdrawal and cooperate with the rear de:

-vices to confine superimposed. lengths of paper -in a taut condition over the writing table, for registry and alinement purposes. The forward arresting devices may be substantially the same as that disclosed in The blades 19, 20 are secured to the under surface o-f'the writing table as the most convenient place. These blades 19, 20 are each intermediately secured to provide opposite free ends for carrying the forward and rearward paper engaging detents. Asboth the blades are duplicates the detailed description will be confined to one. The forward end of, say, blade '19 has a pin 21 fixed thereto, projecting upwardly to engage through a registering aperture in the writing table and also through an aperture in the cross-bar 12 when intercepting the movement of the paper. The blades 19, 20 are connected by cross-bars 22, for being controlled as a unit. The pins 21 are preferably-of segmental form as shown in Fig.

L, presenting a rounded or semi-circular portion toward the forward end of the machine, corresponding in radius to thatof the perforations in the paper. At the rear end of the blade 19 I provide a movable pin 23 having a compound motion transversely to and in the plane of the paper, whereby the pin is adapted to engage through a registering aperture and move with the paper for a limited space or distance and under'a rearward or retarding tension, pulling the paper rearwardly when the paper is engaged with the forward pins to aline the apertures of the several strips over the forward pins and maintain the paper in a taut condition over the writing table. As a plural number of pins 23 are employed for equalizing purposes, it will be noticed that they are fixed to a yoke or slide member 24 having projecting limbs slidably engaged upon the members 19 and 20.. The slide member and pins are thus-unitarily combined: v

The rear pin 23 has a shank portion 2 1 engaged through a longitudinal slot 25 in .the blade 19 and held in position by a crosspin 26 projecting through the,shank 245 and adapted to move forwardly upon the blade 19 against the resistance of the spring'27, said spring having one end fixed or rigidly secured to the under surface of the writing table.j'with its opposite end engaged with the shank 24. The spring 27 also serves as means for returning the pin to its normal position after its release from the paper.

The rear pins 2323 each are of seg' .mental or semi-circular form in cross section at their upper ends, and similar in construction to the front or forward pins 21-21 with which they respectively aline, but with their circumferential portions facing opposite to the circumferential portions of the forward .pins. Such segmental form of pin is of advantage in engaging through the apertures of a manifold number of strips when their relative aperture registration is disturbed, as it enables the pin under such.

condition to enter an opening smaller than Y the fullarea of opening formed by the apertures of the several strips when in registration.

Each pin supporting blade 19 exerts an upward force on its pin sutficient to move the pin quickly through a registering perforation in the paper, but. its pressure on the pins, when the pin isengaged against the lower surface of the paper, is not severe enough 'to cause any appreciable retarding influence against the withdrawal of the paper. The pin'23 is adapted to engage through alongitudinal slot 28 in the writing table, and also through a slot in the cross-plate 29 fixed to the side frames in a superposed -relation over the'writing table The crossplate 29 confines the paper over the table and with the table provides a passage through which the paper passes. The crossplate prevents the paper from being raised off of the tableby the pins when engaged under tension against the lower surface of the paper, while the paper is being withdrawn. The slots in said bar correspond and are in alinement with the slots in the writing table. The pins are depressed and disengaged from the'paper when the tear ing-blade is raised for a paper withdrawal operation.

An actuating bar 30 is slidably mounted upon the under'su rface of the writing table and intermediate. of the blades 19 and 20 having its forward end pivotally connected as at 31 to the arm 17 to operate therewith. The bar 30 is provided with the wedge extensions 33, 34L, adapted to, cooperate with the respective blade connecting bars 22 at the forward and rear pin-carrying portions of said blades 19, 20, to depress such blade ends erly confine the paper upon the writing table.

In an operation of the machine after the strips have been properly loaded within the machine and over the writing table, a form length is issued or delivered from the machine by moving' the tearing blade rearwardly, releasing the pins. The tearingblade is raised to enable the operator to take hold of the ends of the strips of paper and v the tearing-blade is held upward with the pins depressed until the paper has been moved sufii'c'iently to "bring the perforations can freely continue until successive sets of perforations register with the pins. In this instance the rear pins normally being spaced from the forward pins a distance greater than the spacing distance of the perforations in p the paper, are the first'to engage through the paper and resistingly move with the paper until the forward perforations engage with i the forward pins, arresting the withdrawal,

.and when'such delivered or issued sheet is re ister their printing data.
